.To all nir/mm .if muy once/11:

.23e it lrnoivn that l, l'loinnrr J. Buiniows, a itiaen ci the ljnited States, and a resident of Buchanan, in the county ot Berrien and ,diete of liiichigan. have invented certain new and useful improvements in Metal Wheels, of which the following is aspecilisation, reference being; had 'to the acco1npanying drawings. v

My inventionrelates to pneumatic tired wheels for vehicles, and is peculiarly applicable to metal wheels and especially those desivned 'or heavy vehicles such as motor tracas, the tires of 'which are necessarily very heavy and diilicult to apply and remove from the wheel. It has for its object to provide an improved construction by which pneumatic tires, even of the heaviest type, may readily he applied. to or removed from the wheel without objectionable cramping oi' the tire or turning,r it at a sharp angle to the rim or Ytelly band ot' the wheel, and also to improve the construction of metal wheels of this type in other respects hereinafter pointed out. accomplish this object as illustrated in the drawings and as hereinafter described. What l regard as new is set forth in the claims.

ln the accompanying drawings,-

Fig. l is a side elevation Qt part of a wheel embodying my invention;

Fig. 2 is a partial cross sectional view; and

Fig. 3 is a detail illustrating part of the rime ln the illustrated embodimentofmy invention, l indicates the hub of the wheel which may be et any suitable design, and 5 indicates vthe .rim which is connected to the hub by an integral web 6, preferably in the form of a dise, the inner portion ot which joins thehub l near the longitudinal center thereof, as shown in Fig. 2. The outer portion of said web is provided withl laterallyextending ribs '7-8 vat opposite sides thereof, which join with thelfelly band or rim 5 adjacent to the margins thereot` toibra-ce the saine. These ribs ,are provided at intervals around the wheel, aslshown in Fig.' Il. yThe hub ffl, ia'n'dfweb .6, together with the ribs 7-,-8,are 'all'castintegralu y ,91' indicates an opening `in fthe outer portion of the web 6 between two of the pairs of ribsy 7-8, which opening' registers with the inner end portion or atransverse slot 10 Specification of Letters Patent. ivi/3'( Qgtgd Illay 1&5, QZZ,

provided in the rini .3. This slot is of suitable width to permit of the passage of the valve stein-'ll oi a pneumatic tube l2, as shown in Figs. 2 and, so that a pneumatic tire casing 13 containing the tube l2 may be slipped upon the rim 5 by bringing,y the valve stem ll into position to move inwardly in said slot. lt will be. noted .tliatntivo of the ribs 8 are provided'atthe opposite Inargins of the opening 9, which ribs are also adjacent to/tlie margins ot' the transverse slot 10, as best shown in Figures l and 2,so that they effectively reinforce the felly band at opposite sides of said slot and compensate for the weakening of the rim inciden-t to the cuttinw away or material to torni the slot.

By this construction the necessity of crarp ing the tire or turning it at a pronounced angle to the telly band when applying or removing the tire, due to the presence of the valve stein, is avoided, andthe Work of applying or removing the tire is greatly facilitated. When the'itire is in position on the rim the valve stem l1 projects into the opening 9 so that it is readily accessible'rom either side ol the wheel o permit the tire to be pumped up or detiat d, las' desired. lll indicates the usual valvesteni cap whic may be applied to the valve stenrll, as shown in Figs. l and 2, ln the construction illustrated, I have shown the tire asbeingl held in place by retaining ring plates 15-16, the ring platel lo being adapted to abut againsta marginal flange l? provided at th inner margin of the rim 5, while the ring plate 1G is held in place by a split locking ring 18 fitted in agroove ll) at or near the opposite margin ot' the rim 5. Any other suitable tire-securing devicesmay, however, be employed, and it will be understood further that instead of applying the tire directly to the rim 5, it may loe carried by a demountable rim in accordance with well un derstood practice. K

So `far as l am aware, no one has heretofore proposed yto provide the telly band of a wheel with a transverse slot to receive the valve stem of a pneumatic tire,` in cnnection with reinorei'ngAv means between the telly` y band and the body othewheel at opposite isides ot' and adjacenilft'o the slot'lfljand the claims hereinafter made are therefore not to bev restricted to the specific construction shown and described, but, einzeptl in "so far @and adjacent to said Slot.
